Errors linked to medication management in nursing homes : an interview study
- 2021
-
In: BMC Nursing. - : BioMed Central. - 1472-6955. ; 20:1
-
Journal article (peer-reviewed)abstract
- BACKGROUND: The number of errors in medication management in nursing homes is increasing, which may lead to potentially life-threatening harm. Few studies on this subject are found in the municipal nursing home setting, and causes need to be identified. The aim of this study was to explore perceptions of errors connected to medication management in nursing homes by exploring the perspective of first-line registered nurses, registered nurses, and non-licensed staff involved in the care of older persons.METHODS: A qualitative research approach was applied based on semi-structured interviews with 21 participants at their workplaces: Seven in each of the occupational categories of first-line registered nurses, registered nurses, and non-licensed staff. Subcategories were derived from transcribed interviews by content analysis and categorized according to the Man, Technology, and Organization concept of error causation, which is as a framework to identify errors.RESULTS: Mistakes in medication management were commonly perceived as a result of human shortcomings and deficiencies in working conditions such as the lack of safe tools to facilitate and secure medication management. The delegation of drug administration to non-licensed staff, the abandonment of routines, carelessness, a lack of knowledge, inadequate verbal communication between colleagues, and a lack of understanding of the difficulties involved in handling the drugs were all considered as risk areas for errors. Organizational hazards were related to the ability to control the delegation, the standard of education, and safety awareness among staff members. Safety issues relating to technology involved devices for handling prescription cards and when staff were not included in the development process of new technological aids. A lack of staff and the lack of time to act safely in the care of the elderly were also perceived as safety hazards, particularly with the non-licensed staff working in nursing homes.CONCLUSIONS: The staff working in nursing homes perceive that the risks due to medication management are mainly caused by human limitations or technical deficiencies. Organizational factors, such as working conditions, can often facilitate the occurrence of malpractice. To minimize mistakes, care managers need to have a systemwide perspective on safety issues, where organizational issues are essential.

GrassPlot - a database of multi-scale plant diversity in Palaearctic grasslands
- 2018
-
In: Phytocoenologia. - : Schweizerbart. - 0340-269X. ; 48:3, s. 331-347
-
Journal article (peer-reviewed)abstract
- GrassPlot is a collaborative vegetation-plot database organised by the Eurasian Dry Grassland Group (EDGG) and listed in the Global Index of Vegetation-Plot Databases (GIVD ID EU-00-003). GrassPlot collects plot records (releves) from grasslands and other open habitats of the Palaearctic biogeographic realm. It focuses on precisely delimited plots of eight standard grain sizes (0.0001; 0.001;... 1,000 m(2)) and on nested-plot series with at least four different grain sizes. The usage of GrassPlot is regulated through Bylaws that intend to balance the interests of data contributors and data users. The current version (v. 1.00) contains data for approximately 170,000 plots of different sizes and 2,800 nested-plot series. The key components are richness data and metadata. However, most included datasets also encompass compositional data. About 14,000 plots have near-complete records of terricolous bryophytes and lichens in addition to vascular plants. At present, GrassPlot contains data from 36 countries throughout the Palaearctic, spread across elevational gradients and major grassland types. GrassPlot with its multi-scale and multi-taxon focus complements the larger international vegetationplot databases, such as the European Vegetation Archive (EVA) and the global database " sPlot". Its main aim is to facilitate studies on the scale-and taxon-dependency of biodiversity patterns and drivers along macroecological gradients. GrassPlot is a dynamic database and will expand through new data collection coordinated by the elected Governing Board. We invite researchers with suitable data to join GrassPlot. Researchers with project ideas addressable with GrassPlot data are welcome to submit proposals to the Governing Board.

Demographic senescence and effects on population dynamics of a perennial plant
- 2019
-
In: Ecology. - : WILEY. - 0012-9658 .- 1939-9170. ; 100:8
-
Journal article (peer-reviewed)abstract
- Demographic rates in plants are usually assumed to be more stage or size dependent than age dependent, and aging is therefore not considered in demographic models. However, little is known about the effect of age on demographic rates, as there still are few studies based on long-term individual-based plant population data that consider both individual age and size. In addition, little is known about how aging of individuals may affect population dynamics. We present analyses of demographic data for three populations of Fumana procumbens collected 1985-2013, on individuals with known year of germination. We modeled age- and size-dependence of the vital rates of survival, growth, fruiting probability, and fruit number using thin plate spline regressions, and constructed an age x size integral projection model (IPM) to project population-level effects of aging. We found strong correlations between age and vital rates in solely age-based vital rate models, where vital rates initially increased with age, after which they stabilized and, in some cases, eventually declined. In survival models with both age and size, the effects of age were statistically significant, whereas size effects were insignificant at two of the sites. For other vital rates, most of the effect of age could be explained by size alone. In addition, including the age effects on survival in the IPM led to lower population growth rates compared to predictions of a size-only IPM. These results illustrate that demographic senescence does occur in perennial plants, which has only been demonstrated clearly in a few recent detailed studies. Moreover, we show that population projections may be overly optimistic if they do not consider plant age. We conclude that the possibility of demographic senescence should be considered in demographic population models, such as those used in viability analyses of threatened species.

Biomechanical properties of common carotid arteries assessed by circumferential two-dimensional strain and β stiffness index in patients with ankylosing spondylitis
- 2021
-
In: Journal of Rheumatology. - : The Journal of Rheumatology. - 0315-162X .- 1499-2752. ; 48:3, s. 352-360
-
Journal article (peer-reviewed)abstract
- OBJECTIVE: Ankylosing spondylitis (AS) is associated with an elevated risk of cardiovascular disease (CVD) related to atherosclerosis, preceded by arterial stiffness. We aimed to examine common carotid artery (CCA) biomechanical properties using ultrasound to calculate β stiffness index (indicating arterial stiffness) and, a more recently developed technique, two-dimensional (2D) speckle tracking strain (indicating arterial motion and deformation, strain) to 1) compare with age- and sex-matched controls and to 2) analyze relationships between strain and stiffness with disease characteristics and traditional risk factors for CVD in AS patients.METHODS: In this cross-sectional study, a cohort of 149 patients with AS, mean age 55.3±11.2 years, 102(68.5%) men, 146 (98%) HLA-B27 positive, were examined. Bilateral CCAs were examined for circumferential 2D strain and β stiffness index. A subgroup of 46 patients were compared with 46 age- and sex-matched controls, both groups without hypertensive disease, diabetes, myocardial infarction or stroke.RESULTS: Mean bilateral circumferential 2D strain was lower in AS patients compared with controls, 7.9±2.6% vs 10.3±1.9%, p<0.001 whereas mean bilateral β stiffness index was higher, 13.1±1.6mmHg/mm vs 12.3±1.3mmHg/mm, p=0.018. In multivariable linear regression analyses strain was associated with age, erythrocyte sedimentation rate, history of anterior uveitis and treatment with csDMARD and/or bDMARD (R2 0.33), while stiffness was associated with age (R2 0.19).CONCLUSION: Both CCA circumferential 2D strain and β stiffness index differed between AS patients and controls. Strain was associated with AS-related factors and age while stiffness with age, suggesting that the obtained results reflect different pathogenic vascular processes.

Geomedia Studies : Spaces and Mobilities in Mediatized Worlds
- 2018
-
Editorial collection (other academic/artistic)abstract
- This book introduces and develops the concept of geomedia studies as the name of a particular subfield of communication geography. Despite the accelerating societal relevance of 'geomedia' technologies for the production of various spaces, mobilities, and power-relations, and the unquestionable emergence of a vibrant research field that deals with questions pertaining to such topics, the term geomedia studies remains surprisingly unestablished. By addressing imperative questions about the implications of geomedia technologies for organizations, social groups and individuals (e.g. businesses profiting from geo-surveillance, refugees or migrants moving across national borders, or artists claiming their rights to public space) the book also aims to contribute to ongoing academic and societal debates in our increasingly mediatized world.

Segregated education as a challenge to inclusive processes : a total population study of Swedish teachers' views on education for pupils with intellectual disability
- 2022
-
In: International Journal of Inclusive Education. - : Taylor & Francis. - 1360-3116 .- 1464-5173. ; 26:14, s. 1367-1382
-
Journal article (peer-reviewed)abstract
- Many pupils with disabilities receive schooling in segregated contexts, such as special classes or special schools. Furthermore, the percentage of pupils educated in segregated settings has increased in many European countries. Studies suggest that there is high commitment to the general ideology of inclusive education among teachers in 'regular' education in many countries. This survey study investigates the views of teachers in segregated types of school about education. A questionnaire was sent out, in 2016, to all Swedish teachers (N = 2871, response rate 57.7%) working full time in special classes for pupils with intellectual disability (ID). On a general level results show that there is a strong commitment to preserving a segregated school setting for pupils with ID, a limited desire to cooperate with colleagues from 'regular schools' and a view that schooling and teaching are not quite compatible with the idea of inclusive education. The results highlight the importance of investigating processes of resistance within segregated schools to the development of inclusive schools and education systems. We argue that, while research and debate about inclusive education are important, both are insufficient without analyses of existing types of segregated schooling.

MEMS-based VCSEL beam steering using replicated polymer diffractive lens

-
In: Sensors and Actuators, A: Physical. - : Elsevier BV. - 0924-4247 .- 1873-3069. ; 142:1, s. 336-345

Journal article (peer-reviewed)abstract
- Abstract. This paper describes a fully integrated micro-optical system, in which dynamic angular control of the beam from a VCSEL (vertical cavity surface emitting laser) is realized by laterally moving a collimat¬ing diffractive lens in the light path. The lens is mounted on a translatable silicon stage, which consists of a frame with an opening for the light to traverse the lens and electro-statically driven comb actuators, by which the lateral movement is achieved. Devices implementing both 1D and 2D scanning have been fabricated and evaluated. Integration of the lens onto the translatable silicon stage is done using a newly developed fabrication process based on hot embossing of an amorphous fluorocarbon polymer. This fabrication process relies on a reversed-order protocol, where the structuring of the optical element precedes the silicon microstructuring. Assembly and packaging of the VCSEL-MOEMS system, using LTCC (low temperature cofired ceramic) technique, is also demonstrated. Optical evaluation of the system and beam steering function shows significant beam deflection for a relatively low driving voltage (~70 V).

In: Analytical Chemistry. - : American Chemical Society (ACS). - 0003-2700 .- 1520-6882. ; 82:4, s. 1535-1539
-
Journal article (peer-reviewed)abstract
- We present a compact platform for biochemosensing based on the combination of a vertical-cavity surface- emitting laser (VCSEL) light source, microelectrome- chanical systems (MEMS)-based microoptics, a specially designed nanoplasmonic sensing chip, and charge- coupled device (CCD) detector. The platform does not require any spectral analyzer for signal evaluation, show- ing good promise for facile integration, neither does it use any microscope setup for the signal collection or imaging. The analytical capabilities of the developed biochemosens- ing platform are demonstrated by evaluation of the protein-substrate (biotinylated bovine serum albumin- gold) and the protein-protein (biotin-NeutrAvidin) bind- ing kinetics, which is further compared to detection based on conventional optical extinction spectroscopy. The instrument is able to detect low femtomoles of adsorbed proteins with the limit of detection comparable to the state-of-the-art research and commercial optical label-free biochemosensors.

Instructional Practices for Pupils with an Intellectual Disability in Mainstream and Special Educational Settings
- 2020
-
In: International journal of disability, development and education. - : Taylor & Francis. - 1034-912X .- 1465-346X. ; 67:2, s. 151-166
-
Journal article (peer-reviewed)abstract
- The inclusion agenda has influenced education systems around the world, resulting in better access to mainstream education for pupils with special educational needs (SEN). While numerous studies have compared outcomes of pupils with SEN in mainstream and special educational settings, research on the specific characteristics of these settings remains scarce. In this study a survey was conducted with teachers of pupils with an intellectual disability in mainstream (N?=?254) and special educational settings (N?=?392) in Sweden to investigate differences in instructional practices between these settings. The results showed that teachers? in the two settings devoted approximately similar amount of time to learner- centred and teacher-centred activities respectively, which slightly more focus on teacher-centred activities in both settings. The results of a Mann-Whitney U-test revealed that teachers in mainstream educational settings, in comparison with teachers in special educational settings, reported significantly higher expectations of pupils? performance but lower focus on supporting pupils? social participation. Support of pupils? social participation may be an important characteristic of special educational settings, and there is a need to further explore how knowledge of teacher practices in special educational settings may be used to support pupil?s social participation in mainstream settings.

Birth weight, adulthood BMI, and subsequent weight gain in relation to leptin levels in Swedish women
- 1999
-
In: Obesity Research. ; 7, s. 150-154
-
Journal article (peer-reviewed)abstract
- Department of Internal Medicine, Göteborg University, Sweden. Lauren.Lissner@medfak.gu.se OBJECTIVE: Leptin seems to be involved in the regulation of energy balance, although little is known about the epidemiology of leptin with respect to prediction of weight gain and incidence of obesity-related diseases. The dual aim of this study is to document characteristics of leptin after long-term storage, and to describe its relation to body weight, from birth to old age, in an ongoing prospective study. RESEARCH METHODS AND PROCEDURES: A population-based sample of Swedish women was first examined at the ages of 38 to 60 and re-examined 24 years later. This study used 1358 frozen serum samples that had been stored 29 years for analysis of leptin concentrations and their relation to body weight history. RESULTS: Leptin values obtained from stored samples showed the same correlation with relative weight as that seen in a contemporary sample with similar demographic characteristics. Lower self-reported birth weight was associated with higher leptin levels in adulthood (p = 0.01), controlling for age and adult BMI. Prospective analyses revealed that high leptin in 38 to 46-year-olds predicted subsequent long-term weight gain (p = 0.003), although no significant associations were seen in women initially aged 50 or older. DISCUSSION: It is feasible to use frozen serum for studying leptin in relation to obesity and related developments many years later. High leptin level was a risk factor for subsequent weight gain in 38- and 46-year-old women. Retrospective analyses involving birth weight suggest that leptin resistance in adulthood might have fetal origins. PMID: 10102251 [PubMed - indexed for MEDLINE]

Effects of bariatric surgery on cancer incidence in obese patients in Sweden (Swedish Obese Subjects Study): a prospective, controlled intervention trial.
- 2009
-
In: The lancet oncology. - 1474-5488. ; 10:7, s. 653-62
-
Journal article (peer-reviewed)abstract
- BACKGROUND: Obesity is a risk factor for cancer. Intentional weight loss in the obese might protect against malignancy, but evidence is limited. To our knowledge, the Swedish Obese Subjects (SOS) study is the first intervention trial in the obese population to provide prospective, controlled cancer-incidence data. METHODS: The SOS study started in 1987 and involved 2010 obese patients (body-mass index [BMI] >or=34 kg/m(2) in men, and >or=38 kg/m(2) in women) who underwent bariatric surgery and 2037 contemporaneously matched obese controls, who received conventional treatment. While the main endpoint of SOS was overall mortality, the main outcome of this exploratory report was cancer incidence until Dec 31, 2005. Cancer follow-up rate was 99.9% and the median follow-up time was 10.9 years (range 0-18.1 years). FINDINGS: Bariatric surgery resulted in a sustained mean weight reduction of 19.9 kg (SD 15.6 kg) over 10 years, whereas the mean weight change in controls was a gain of 1.3 kg (SD 13.7 kg). The number of first-time cancers after inclusion was lower in the surgery group (n=117) than in the control group (n=169; HR 0.67, 95% CI 0.53-0.85, p=0.0009). The sex-treatment interaction p value was 0.054. In women, the number of first-time cancers after inclusion was lower in the surgery group (n=79) than in the control group (n=130; HR 0.58, 0.44-0.77; p=0.0001), whereas there was no effect of surgery in men (38 in the surgery group vs 39 in the control group; HR 0.97, 0.62-1.52; p=0.90). Similar results were obtained after exclusion of all cancer cases during the first 3 years of the intervention. INTERPRETATION: Bariatric surgery was associated with reduced cancer incidence in obese women but not in obese men.

Effects of bariatric surgery on mortality in Swedish obese subjects.
- 2007
-
In: The New England journal of medicine. - 1533-4406. ; 357:8, s. 741-52
-
Journal article (peer-reviewed)abstract
- BACKGROUND: Obesity is associated with increased mortality. Weight loss improves cardiovascular risk factors, but no prospective interventional studies have reported whether weight loss decreases overall mortality. In fact, many observational studies suggest that weight reduction is associated with increased mortality. METHODS: The prospective, controlled Swedish Obese Subjects study involved 4047 obese subjects. Of these subjects, 2010 underwent bariatric surgery (surgery group) and 2037 received conventional treatment (matched control group). We report on overall mortality during an average of 10.9 years of follow-up. At the time of the analysis (November 1, 2005), vital status was known for all but three subjects (follow-up rate, 99.9%). RESULTS: The average weight change in control subjects was less than +/-2% during the period of up to 15 years during which weights were recorded. Maximum weight losses in the surgical subgroups were observed after 1 to 2 years: gastric bypass, 32%; vertical-banded gastroplasty, 25%; and banding, 20%. After 10 years, the weight losses from baseline were stabilized at 25%, 16%, and 14%, respectively. There were 129 deaths in the control group and 101 deaths in the surgery group. The unadjusted overall hazard ratio was 0.76 in the surgery group (P=0.04), as compared with the control group, and the hazard ratio adjusted for sex, age, and risk factors was 0.71 (P=0.01). The most common causes of death were myocardial infarction (control group, 25 subjects; surgery group, 13 subjects) and cancer (control group, 47; surgery group, 29). CONCLUSIONS: Bariatric surgery for severe obesity is associated with long-term weight loss and decreased overall mortality.
